I was down at R - Tech on wednesday having a k03s map. My car is a AGU with a k03s and forge tip. The car was only boosting 18 psi and it should be around 20-22 psi.
The guys had a good look around and couldnt find anything wrong and come to the conclusion it's probably the actuator that needs adjusting. The k03s come off a seat ibiza and has done 40k miles but was checked out by a turbo specialists in wakefield before I bought it at a cost of £25 + vat. They said it was perfect. I mention this just to give you guys a little info before answering my question.

Now my question is when im hitting full boost in any gear there is a whining noise that sounds like its coming from the turbo. COULD THIS BE DUE TO THE ACTUATOR NOT BEEN SETUP CORRECTLY AND THE WASTEGATE NOT OPENING/CLOSING PROPERLY? Nick at R - tech drove the car whilst it was making this noise but didnt even mention it.

Anyone got any ideas?
cheers
